About Optimised Battery Charging
Optimised Battery Charging is designed to engage only in locations where you spend the most time, such as your home and place of work. After you’ve set up your iPhone, Optimised Battery Charging needs at least 14 days to learn your charging habits, so it won’t engage before then. Also, your iPhone needs to have at least nine charges of five hours or more in a given location for Optimised Battery Charging to engage.
The feature doesn’t engage when your charging habits are more variable, when you travel or if you charge for short periods of time. Because of this, some location settings must be enabled for Optimised Battery Charging to activate. None of the location information used for this feature is sent to Apple.
Go to Settings > Privacy & Security > Location Services and turn on Location Services.
Go to Settings > Privacy & Security > Location Services > System Services and turn on System Customisation.
Go to Settings > Privacy & Security > Location Services > System Services > Significant Locations and turn on Significant Locations.
